CriteriaEvaluator - Global

concept australia Updated Sep 10, 2026 1 min read c_CriteriaEvaluatorAPI.md

The CriteriaEvaluator script include provides methods to implement a general-purpose criteria evaluator.

The general use pattern is to construct the class, add as many criteria as needed, then evaluate.

CriteriaEvaluator - addCriterion(String lhComparand, String operator, String rhComparand)

Adds the criteria to be evaluated.

Name	Type	Description
lhComparand	String	The left hand comparand. Must be a named value in the left hand values input into evaluate().
operator	String	The operator. Must be one of: equals, starts with, contains, does not contain, ends with, or regex matches.
rhComparand	String	The right hand comparand. Can be evaluated either as one of the right hand values input to evaluate() or as a literal string.

Type	Description
void

CriteriaEvaluator - evaluate(Object lhValues, String rhValues, Boolean any)

Evaluates the criteria.

Name	Type	Description
lhValues	Object	A hashmap of name-value pairs to evaluate the left hand comparands of the criteria.
rhValues	String	Optional right hand values to use instead of the literal value in evaluating the right hand comparands.
any	Boolean	If true, any criterion matching suffices for a true result. If false, all criteria must match for a true result.

Type	Description
Boolean	True if the supplied values satisfy the criteria, false otherwise.
